To all whom it concern} Beit known that I, J ULIUs BRENZINGER, a

York, have invented new and useful Improvements in Oap-Flanging Machines, of which the following is a specification;

This invention relates to a machine for attaching a ca to a bottlejjar, or other rece tacle, and tiereby closingthe latter. T e

. cap consists,-essentiall ,of a resilient band 7 having a lower flange t at engages below the head. of the bottle and of a disk or cover which rests u on the mouth of the same and is surrounde by theband. Thus by upset- 1 ting the upper edge of the band against the cover the two component parts of the cap are united and the bottle is closed.

The machine consists, essentially, of a table or support from which the bottles are adapted to be sus ended and which-presents them to a set 0 rotatory Hanging-rollers.

machine, Fig. 1 a detall of theyoke;

These rollers upon descending engage the band above-referred to-and'upset the same against the cover to close the bottle. 'By

suspending the bottles from the su port dur-.

ing the flanging operation the wor mg pres- .sure is taken up by the comparatively heavy heads 'of the bottles and not by their bodies, so that breakage is avoided.

Theletter A indicates the 'bottleor other A is'theband that embraces clamp v the mouth of the bottle, projects above the same, and has a lower.fiangeM, which engages underneath tends above acover A and also,.if desired, a acking A that is placed upon the bottle. he machine u sets the upwardly-projecting the head The band A incloses and ear I section of ban .A, Fig. 13, again t th cover, a

B-indicates t e frame of the machine, having a fixed shaft or standard B, that is embraced by the hubs of a rotatory feed table or sup ort a, the hub resting upon an offset B of ame B. The bottles A to be closed are adapted to be suspended by their heads from table. a, which presents them -succes-' sively tothe flanging-head hereinafter described. Means are provided for imparting an intermittent rotatory -movementto the table, the relative-arrangement of the parts being such that the-table is at rest while the flan ing-rollers act to close the bottle.

' T e means for imparting intermittentrotatory movement to the table care as follows: In suitable bearin s of frame- B turns-the driving-shaft I), which by pulley b and belt I)? rotates a pulle c, loose on worm-shaft c, to which it is a aptedto be coupled by a clutch c The worm c of shaft 0 intergears with aworm-wheel d, faston an upright shaft (1, that also carries a crank-disk To the latter is fulcrumed at (1 a link (1 pivoted at d to a lever e}which is loosely mounted upon. hub a, Fig, 2. A spring-influenced pawl e, pivoted to lever e at 6 is adapted to engage the teeth of a ratchet-disk e clamped to hub 0/. Thus each rotation'of shaft (1 will by pawl e" advance disk a for the distance of one tooth, the disk being at rest when the pawl recedes. Inthisw'ay the desired intermittent rotatory movement is imparted to disk and consequently to table a.

The'bottles A to be closed are suspended from table. a, in the following manner: The

table is provided with a series of peripheral notches, the number of which corresponds to the number of teethon disk e"; At each notch there is mounted upon the disk thefixed member f of a clamp, to which the movable'me'mber or jaw f 'is hinged at f The f when closed is adapted to embrace t e neck of the bottle 'A,-.which is thus s spended therefromby-its head-A This head is supported upon inwardly-projecting fiber gaskets j, which are secured to the clam b 1 top ,lates f To member f is pivoted at f SI; hook or catch f influenced by a spring f and having a tallplece f. The hook f is designed to engage either one of a pair of keepersf f on jawf'. The attendant after fitting the bottle in pos tlon swings jaw f inward by a handle f so that the hook f 7 falls behind first keeper f As the table a now advances a projection f on jaw f encounters a roller f journaled in frame B, and forces jaw f inward to such an extent that the hook f 7 falls behind the second keeper f. In this way the clamp is tightly closed without unnecessarily taxing the strength of the attendant. After the fianging operation has been completed and the closed bottles are again 'carried within reach of the operator the tail f encounters a roller f ijournaled in an arm f cramped to fixed shaft B. The roller will thus open hook f to disengage keeper f and permit j aw f to be thrown open by springs f The bottle, being thusreleased, will drop upon a suitable chute. (Not shown.) The members ff are of such a size that they will not press laterally against the bottle, any rotation of the latter during the flanging operation being prevented by inwardly-projecting elastic buffers f In Fig. 7, X indicates the position of the clamp when partly closed around the inserted bottle. X shows the clamp completely closed, the bottle being here acted upon by .the flanging-rollers. At X X X are shown successive positions to which the bottles are carried, while X shows the clamp open with the bottle dischar ed.

The means for anging the bottle-cap con- .sist of a suitable number of flan ing-rollers g,

which are so profiled as to turn t e projecting end of band A, Fig. 13, inward and against cover A, Fig. 14. The rollers g turn on shafts g, carried by bent hangers g which are secured to a rotatable and vertically-movable flanging-head h. The hangers g are adjustable in radial grooves h of head it by means of slots 9 and set-screws 7L2, so that the flanging-rollers may be properly set. Intermediate the rollers 9 there may be secured to head it guide-rollers t, turning on arbors i, which are carried by the radially-adjustable slides i Figs. 8 and 9. The head his-1nounted upon an upright shaft j, carrying fast pulley j, that receives continuous rotatory movment from a pulley b on shaft b by belt I). The shaft is vertically or axially movable to first lower head h and brin rollers 9' into enga ement with the cap an to then raise the rol ers ofl the cap.

The means for imparting the axial movement to shaft are as follows: Shaft d carries I a cam (i adapted to oscillate a lever 7c, fulcrumed at 7r to an elbow-lever Z. Lever has a roller P, which is drawri against cam d by a spring is. A yielding connection is formed between the levers ls Z by means of pins m passing theretln'ough and carrying elastic buffers m, which are interposed between the levers. This yielding connection permits the rollers g to adjust themselves to slight variations in the height of the bottleheads. To the upper arm of lever Z is fulcrumed at n a yoke n, the lower member or cross-piece n of which is perforated at n. Through the perforated member passes the upper end of shaft j, which is provided above perforation n with a collar j and a pin Each complete rotation of shaft (1 will cause an oscillation of lever Z on its fulcrum Z, so that when its upper arm descends it will by bearing upon pin j lower shaft 3', and conse quently head It and rollers g. When such upper arm rises, the shaft j will be lifted by the engagement of member a with collar The machine is so timed that the engagement of the rollers g with the cap takes place while table a is at rest. The shaft j projects beneath head h, and into its lower socketed end is fitted a pin 0,having head 0, Fi 10. This pin is embraced by the sleeve 1) of a chuck p, which is made to bear upon cover A by spring p The chuck p is recessed at a to receive head 0 which thus holds the c uck to the pin. Interposed between spring 11 and shaftj is a ball-race q. Upon the descent of shaft j the chuck p, which is centered between rollers g, engages cover A in advance of the enga ement of band A by the rollers. The chuc lk will thus ress the cover tightly against the bottle-head and the latter against its seat f ofclamp f f in advance and during the flanging operation. The ballbearing meanwhile permits the chuck p to remain stationary through its frictional con tact with cover A while shaft j is free to rotate axially.

It is desirable to provide means for positively locking the table a against rotation while the flanging rotation is going on. Such means are shown to consist of a series of perforations e in ratchet-disk e Fig. 2, one perforation being provided for each tooth of the disk. The perforations c are successively engaged by a vertically-movable bolt 1", influenced by a spring r and having a lower head 7. Against this head bears one arm of a ca'm-lever s, fulcrumed at s and carrying on its other arm a cam-roller s Thclatter engages a cam d fitted on shaft d. It will be seen that by the above-described mechanism the bolt will be alternately raised and lowered during each rotation of shaft d, so as to first lock and then release disk e, and conse uently table a.

s has already been stated, the pawl-andratchet mechanism e e imparts an intermittent rotatory movement to table a. The periods of rest of the table are utilized by the attendant to suspend a new bottle from the table. It is desirable that these periods of treadle t clutch c rest may-be prolonged, if so desired, so that the operator may have his: own time for securin each bottle in position. Means are there ore provided for automatically stopping the shaft (1 upon each complete rotation and for restarting it whenever desired; These means are shown to consist of a disk (i Fig. 5, carried by shaft-d and having notch d". The latter is adapted. to be en aged b' a roller t, j ournaled to an arm t o a tread e t, which is influenced b a spring't Treadle t is fast on a rock-shaft t carrying a lever t which has a forked end It. Thefork grasps the lower end of a shipping-lever t, influenced by a spring t and embracing with its upper forked end i the clutch 0 will couple pulley c to worm-shaft c, and thus start the rotation of shaft d. -As the shaft rotatesthe roller t will ride along the solid section of disk (i to maintain the coupling in its closed osition. When the shaft (1 has completed a ll rota-. tion, roller t will by spring t be drawn into notch d to raise treadle t, open clutch c and stop shaft d; In this way the table a will be arrested and the flanging-rollerswill be held in their raised osition until the treadle t is again depresse by the operator.
